Extraterrestrial: The First Sign of Intelligent Life Beyond Earth

This would make ‘Oumuamua’s geometry more extreme by at least a few times in aspect ratio—or its width to its height—than the most extreme asteroids or comets that we have ever seen.

while we cannot control the data that the universe provides, we can control how we go about seeking it, assessing it, and recalibrating our future scientific undertakings. The world of possibilities to which we choose to open ourselves, bounded by the evidence we collect and that we allow our collective intelligence to consider, very much determine

One of the most difficult lessons to impart to young scientists is that the search for the truth can run counter to the search for consensus. Indeed, truth and consensus must never be conflated.

Today, a young theoretical astrophysicist is more likely to get a tenure-track job by pondering multiverses than by seeking evidence of extraterrestrial intelligence. This is a shame, especially because budding scientists are often at their most imaginative during the early phases of their careers. During this fertile period, they encounter a profe

Long before I confronted the evidence presented by ‘Oumuamua, I had learned that across all facets of life, taking the evidence presented to you and pursuing it with wonder, humility, and determination can change everything—if, that is, you are open to the possibilities contained in the data.

As I have mentioned, when ‘Oumuamua sped part of the way around the Sun, its trajectory deviated from what was expected based on the Sun’s gravitational force alone. There was no obvious explanation for why.

In addition to being small and oddly shaped, ‘Oumuamua was strangely luminous. Despite its diminutive size, as it passed the Sun and reflected the Sun’s light, ‘Oumuamua proved to be relatively bright, at least ten times more reflective than typical solar system asteroids or comets. If, as seems possible, ‘Oumuamua was a few times smaller than the

Sometimes, by near accident, something exceptionally rare and special crosses your path. Life turns on your seeing clearly what’s in front of you.

For scientists, what remains of a theory after its contact with data is what is deemed beautiful.
